In the finale, the crown prince (Won) became king and eventually brought order back to Goryeo. Having done his part, he abdicated the throne back to his father.
During his 10 lost years in his unlikely stay in Yuan, it was not told whether he was able to be with Lin and So Hwa who were still hiding and seen in Goryeo at that time. Yuan would not be a welcoming place to Won with his grandfather emperor already passed away and Won having no roots whatsoever in a land of different language.
Many years after his return, Won's painting was found. There, the three of them happily spending time in the flowery meadows gives off a touching vibe that they were able to live out their friendship and not necessarily that they were separated permanently after all.
